Sennheiser isn’t waiting around for its consumer business questions to get sorted out. In 2026, the brand is pushing forward where it still carries real weight, professional audio, with the launch of the $479 HD 480 PRO, a closed back studio headphone that builds on the open back HD 490 Pro introduced in 2024.
Positioned at the top of its 400 series closed back lineup, the HD 480 PRO is aimed squarely at working environments like tracking, monitoring, and live use where isolation actually matters. Sennheiser is framing it as its most versatile pro headphone to date, designed to handle recording and production duties while still being usable for critical mix decisions. Patents covering fit, comfort, and noise decoupling suggest this is more than a simple closed back variation.
More importantly, it’s a reminder that while the company’s consumer side direction remains uncertain, the pro division is still doing what it has always done, building tools that people in studios and on stages can rely on.
The HD 480 PRO is designed to address two common issues with closed back headphones: inconsistent bass accuracy and long term comfort. Sennheiser is aiming for controlled, reliable low end while keeping the fit comfortable enough for extended use in recording, tracking, and monitoring across studio, live, and mobile workflows.
Achieving accurate low-end performance in a closed-back design has always been a balancing act. Isolation helps with tracking, but it often comes at the expense of bass control and realism. That’s the gap Sennheiser is trying to close with the HD 480 PRO.
“With closed-back headphones, a good reproduction of the low-end is usually difficult to achieve. This is where the HD 480 PRO excels. Compared to other closed-back headphones, they are a lot tighter on the bass, their low-end is super-accurate and realistic,” notes Jimmy R. Landry, Category Market Manager, Music Industry at Sennheiser.
Whether used in the studio by producers, mixers, musicians, and recording engineers, or in live settings by FOH and monitor engineers, the HD 480 PRO is positioned as a flexible tool for monitoring, recording, and production, with the added claim that it can be used for mixing. Sennheiser is targeting users who need a consistent reference across different environments, including mobile use.
The tuning focuses on accuracy and a relatively neutral frequency response, with controlled low end intended to translate reliably across other systems, whether that’s home speakers, car audio, or PA setups.
“Knowing that you can rely on what you’re hearing is everything; that’s what you get with the HD 480 PRO.” Jim Kaufman, producer
“When I’m going to be mixing on headphones outside my studio, it’s imperative I have a pair that I trust. With the HD 480 PRO, to have this level of quality and accuracy in a closed-back headphone is amazing.” Will Brierre, mix engineer
“As producers, we have to receive the best sound to our ears that we can. Every detail is important. When you’re wearing the 480s, you’re immersed in the sound, completely undistracted by the outside world.” Young Chencs, artist and producer
The HD 480 PRO uses 38mm dynamic drivers with neodymium magnets, paired with lightweight voice coils intended to improve efficiency and overall responsiveness.
The HD 480 PRO uses a multi-stage passive isolation design to help reduce external noise and keep the focus on the signal. The ear pads include grooves to accommodate glasses, which helps maintain a more consistent seal, an important factor for stable bass and overall accuracy. Angled earcups position the drivers more precisely, with the goal of delivering a consistent listening experience.
“Comfort is of paramount importance when headphones are a work tool,” adds Gunnar Dirks, Senior Product Manager for professional headphones. “Engineers often spend hours on end in their sessions. They need a lightweight, ergonomically designed pair of headphones to keep focus and concentration up. The HD 480 PRO eliminates any pressure points and fit every head precisely and comfortably even if you’re wearing glasses.”
Like the open-back Sennheiser HD 490 PRO, the closed-back Sennheiser HD 480 PRO is a wired-only design. To add some flexibility, it includes input jacks on both earcups for detachable cables, allowing users to choose their preferred configuration or adapt to different studio setups. The earcups are also angled to position the drivers more precisely, with the goal of maintaining a consistent listening experience.
A series of design features grouped under the term “Vibration Attenuation System” eliminates unwanted vibration, reflections, and distortion, preserving the clarity of the signal. Ultralight voice coils ensure authentic and dynamic reproduction.
Like its open-back counterpart, the HD 490 PRO, the HD 480 PRO benefits from several Sennheiser-patented features.
Special Axes Geometry: The mechanical design of the 480 enables the headphones to optimally adapt to the head and maintain an equal contact pressure no matter what the shape of the user’s head. The listening experience is consistent across users.
Comfort Zone for Glasses: The ear pads are designed to avoid excessive pressure on the temples, using a softer contact zone that helps maintain a proper seal while improving long-term comfort.
Blocking Cable-borne Noise: A coiled section near the earcup connector helps reduce cable-borne noise, limiting the transfer of mechanical vibrations from handling or contact with surfaces like a desk into the earcups.
The detachable cable can be connected to either the left or right earcup, allowing for more flexibility depending on the setup and helping keep the cable out of the way during tasks like instrument tracking. The earcups are also braille-marked for easier identification. Designed by Sennheiser’s professional team, the HD 480 PRO is built with long-term use in mind and aimed at delivering consistent performance over time.
The open-back HD 490 PRO and closed-back HD 480 PRO are at the top of the 400 series of purpose-built professional audio headphones. So which one is best for which application?
“Our developers have been working painstakingly to bring the sound of the closed HD 480 PRO as closely as possible to that of the open HD 490 PRO. Which model is the better choice for you really depends on how you work,” explains Gunnar Dirks. “The open HD 490 PRO will be ideal for mixing in quiet environments, while I would recommend the closed HD 480 PRO for applications where you need isolation, for example, when you’re tracking vocals in the room, when monitoring or using them as an FoH reference, or simply when you’re working in the same space as others.”

There’s some uncertainty around Sennheiser’s consumer business, but the professional side remains separate for now, which means products like the HD 480 PRO and HD 490 PRO are not directly affected.
The HD 480 PRO (and PRO Plus) stands out for its focus on flexibility within a closed-back design—dual-sided cable entry, attention to long-term comfort, and an effort to deliver more controlled low-end performance than is typical for this category. It’s clearly built as a working tool rather than a lifestyle product.
What’s missing is anything beyond wired connectivity and a broader feature set—there’s no DSP, no wireless option, and no attempt to blur the line into consumer use. That’s intentional, but it narrows the audience.
Competition is strong across multiple price points, including the Beyerdynamic DT 770 PRO X and Beyerdynamic DT 990 PRO X at the lower end, and models like the Final DX3000CL and Meze Audio Strada further up the ladder.
These are aimed at professionals and serious creators who need a consistent, reliable reference for tracking, monitoring, and potentially mixing, especially in environments where isolation matters. The decision ultimately comes down to fit and comfort as much as sound, which makes a hands-on demo less of a suggestion and more of a requirement.
The Sennheiser HD 480 PRO retails at $479 USD (MSRP). These headphones come with recording earpads, a 9-foot coiled cable, and a carrying bag.
If you prefer, the HD 480 Pro Plus has the same features and accessories as the HD 480 Pro but includes a hard travel case for $519 at Amazon.
Alternatively the Sennheiser HD 490 Pro and Pro Plus open-back headphones are also available for $429 / $499 at Amazon.

For years, existing consumer platforms have tried to keep users within their app by offering more services. After the rise of the AI chatbot, the trend is to have people use the assistant for both queries and actions without leaving the conversational flow. With its latest update, Yelp is letting people ask questions, get restaurant reservations, order food delivery, and book service professionals, all through its updated AI assistant.
The company debuted the AI assistant in 2024 to help people search for different services based on their problem. It is now using the platform data paired with an AI assistant to let users do more tasks.
In a demo seen by TechCrunch, the company’s SVP of product, Akhil Kuduvalli Ramesh, searched for hiking places to go with a dog without a leash; looked for takeout places along the way, with an option to place an order on Doordash; looked for restaurant recommendations for a weekend plan, with an option to check out availability and book a table; and queried about painting a friends’ new Victorian house without leaving the chat.
“We would really like consumers to reconceive Yelp as a place where they can ask questions and get answers, not just that, but also complete the action. That’s Yelp reconceiving from a review platform to an answers and action platform,” he told TechCrunch over a call. “Some of the investments we’re making will be in that lane.”
Users can select a specific page for a restaurant or service when they tap on it, or ask more questions about the business. Yelp said that as the knowledge is grounded in details of the business on the platform, the business’s website, and user reviews, there is a scant chance of getting wrong answers.
The company is hosting the assistant in a new tab in the app, which is now placed in the center of the bottom navigation bar, so users are likely to visit it more often. The assistant will be available on iOS and Android at launch and will work with all businesses, including restaurants, retail shops, and attractions. The company said that the desktop version and rollout across all kinds of businesses are slated for later in the year.
Apart from fetching information, Yelp also announced integration with external providers to complete an action, like place an order or appointment. Users can now order food through DoorDash and Grubhub, book fitness or beauty appointments through Vagaro, a doctor’s appointment through ZocDoc, and a car repair through Repairpal. Plus, it also offers a Calendly integration for other kinds of businesses that allow appointment booking.

Notably, all these actions will lead you to a specific provider’s app or page, meaning this is not “agentic” in nature, where the entire transaction is completed within the chat window. Kuduvalli mentioned that while the redirections are the way Yelp is set up now, it might not “remain that way” in the future.
However, it’s hard to say how agentic pipelines might work with other services for cases when the user doesn’t specify whether they want to order food through DoorDash or Grubhub.
Besides the new AI assistant, Yelp is rolling out a few quality-of-life updates to the app. Last year, it launched the ability for people to scan a menu and see what dishes look like through photos other users posted. Now, users can look at those dishes within the app as they are scanning a menu.
What’s more, Yelp said that users will be able to search the media gallery of a business using natural language queries instead of keywords. Plus, the company will offer an AI-powered tagging and grouping feature for before and after photos to business owners to avoid manual work.
Electron Impressions encountered a problem that every aluminum foundry is all too familiar with: hydrogen gas seeping into molten aluminum and forming small gaps as the metal cools and hardened. Most people strive to remove those bubbles, but he chose to put them to good use instead.
Liquid aluminum absorbs hydrogen in much the same manner that water absorbs carbon dioxide. Water vapour in the air reacts with the hot metal surface, forming aluminum oxide and free hydrogen. At that point, the liquid metal breaks down the hydrogen molecules into individual atoms, which then dissolve directly into the melt. Sieverts’ law describes how much hydrogen is allowed in, and it all boils down to the square root of the gas pressure above it. So, if you boost the pressure slightly or keep the metal hot long enough, a lot of hydrogen will flow in.
However, once the melt begins to cool, solubility plummets dramatically. The gas in the solution just leaves and creates bubbles. And then, as the metal hardens, every last bit of hydrogen is pushed back out. The surrounding solid then retains the bubbles, making them permanent voids. Foundries typically consider this as a fault and attempt to eliminate it, but Electron Impressions saw a chance to intentionally create the holes and then fill them with something far superior.
He chose to work with an aluminum-copper alloy because it responds well when cooled. The combination reaches a temperature where one phase, known as theta or Al2Cu, begins to form first. So, by keeping the hydrogen-rich melt molten for a little longer, he ensured that the gas was absorbed thoroughly and uniformly. A steady steam of water vapor bubbled in through the crucible, providing both the necessary reaction and fresh hydrogen. Every single bubble left behind a thin layer of aluminum oxide. However, the majority of the action occurred within the liquid itself.
Once the alloy had absorbed enough hydrogen, he reduced the cooling rate. As the gas left the solution, the first huge voids appeared. Inside those enclosed regions, the theta phase could expand without influence from the surrounding liquid. Crystals began to form on the walls of the hydrogen bubble gradually, while the remainder of the alloy remained liquid for a little longer since its composition had not yet reached the final eutectic point. Then he poured out the remaining liquid, leaving the crystals in their own hollow chambers.
What you get resembles a metal geode. Slice it open to reveal a cavity lined with shiny metallic crystals looking back at you. These crystals only formed in the reducing environment provided by the hydrogen, thus they remained clean and free of any excess oxide layers. The amount and size of crystals vary depending on the copper content and cooling speed. More copper yields fewer thicker crystals. Less copper yields many smaller ones. Slow cooling favors the hydrogen-bubble approach, whereas quicker cooling is useful when you merely want to get the liquid out of the way and drain it out quickly.

Every business seems to think that its customers want more AI. Yelp is the latest to add more artificial intelligence tools. The review site has upgraded its Yelp Assistant, an agentic AI chatbot, to work across all of Yelp’s categories. Yelp Assistant was initially launched in 2024 with a limited scope and then expanded in 2025.
With the latest update to its chatbot, Yelp Assistant can handle natural language queries for finding a specific local business. It can also be used to take some additional actions, such as making a restaurant reservation or ordering takeout. Yelp’s spring product updates introduced new third-party integrations with Vagaro, ZocDoc and Calendly. Yelp Assistant can also use these integrated services for booking appointments in related fields. The chatbot now has a dedicated Assistant tab in the iOS and Android apps, and it can also be accessed directly from business pages for certain fields, such as restaurants and retail shops. Support for all business types and a desktop version are planned for later in 2026.
Other AI features coming to Yelp include a personalized home page on mobile and extra photo discovery tools.
41-year-old Angelo Martino, a former employee of cybersecurity incident response company DigitalMint, has pleaded guilty to targeting U.S. companies in BlackCat (ALPHV) ransomware attacks in 2023.
Together with two other Sygnia and DigitalMint ransomware negotiators (33-year-old Ryan Clifford Goldberg and 28-year-old Kevin Tyler Martin), Martino was charged with conspiracy to interfere with interstate commerce by extortion, interference with interstate commerce by extortion, and intentional damage to protected computers.
Martino was initially identified only as “Co-Conspirator 1” in an October 2025 indictment, but was named in court documents unsealed in March. Martin and Goldberg also pleaded guilty to conspiracy to obstruct commerce by extortion and are facing up to 20 years in prison each.
According to court documents, while working as a negotiator for five victims, Martino shared confidential information about the victims’ negotiation positions and insurance policy limits with BlackCat ransomware operators, helping the cybercriminals extort the maximum possible amount.
Between April 2023 and April 2025, he was also involved in BlackCat ransomware attacks alongside accomplices Kevin Tyler Martin and Ryan Goldberg.
While operating as BlackCat affiliates, the three defendants demanded ransom payments and threatened victims to leak data stolen before encrypting their systems. Prosecutors added that the three accomplices paid the BlackCat administrators a 20% share of all ransoms proceeds for access to the ransomware and extortion portal.
Their victims included at least five U.S. organizations, among them a financial services firm that paid $25,660,000 and a nonprofit that paid a $26,793,000 ransom, as well as law firms, school districts, medical facilities, and other financial services companies.
DigitalMint CEO Jonathan Solomon told BleepingComputer that the company condemned the previous malicious conduct and noted that Martin and Martino were fired after their actions were discovered.
“We strongly condemn these former employees’ criminal behavior, which violated our values, ethical standards, and the law. When we learned about the conduct, we immediately terminated both individuals,” Solomon said.
The BlackCat ransomware operation has been linked by the FBI to more than 60 breaches between November 2021 and March 2022. In a separate advisory, the bureau added that the cybercrime gang collected at least $300 million in ransom payments from over 1,000 victims through September 2023.

Rooms come alive as thousands of LEDs illuminate in perfect time over a large 50×50 panel. Chris Maher took on this task by converting regular light strips into that massive display without breaking the bank or requiring several controllers. His finished presentation plays well on a single 12-volt power supply and some pretty tiny gear, offering professional-looking animations, text, and patterns.
Chris purchased 18 5-meter rolls of 12-volt SK6812 strips, each with 30 LEDs per metre, so obtaining the necessary components was simple. He then sliced each roll into three 50 LED portions, for a total of 54 segments, plus a few spares for safety. To provide support, he built a simple wooden frame out of one-by-two boards and some board-and-batten panels. The rest of the kit consisted of a few short sections of 18-gauge silicone wire, lever-style connections, rubber grommets, and a Gledopto 4D-EXMU controller loaded with WLED firmware, as well as a standard 12-volt power supply.

First, he had to get the strips ready to go, so he carefully removed the connections from the ends, soldered the exposed pads, stripped, tinned, and prepared all of the wires for connection. This preliminary work made the final assembly a lot simpler. Next came the frame, which he built by stacking and screwing the boards together to form a solid rectangle the same size as the finished grid. He added some board-and-batten panels to the front to provide a firm surface to screw the strips to. He painstakingly wrote out the places of each strip, ensuring that they were perfectly spaced from edge to edge. He then placed the strips down in a zig-zag pattern, alternating direction row by row, to form a single long continuous data channel.
Holes were drilled above and below each strip, and rubber grommets were inserted to allow the wires to pass through to the back side while keeping the front of the display neat and free of connections. At several spots, lever-style connectors were utilized to connect the power and data lines, and separating the grid into four distinct data runs ensured that everything remained in sync.
The wiring was rather simple, as you just connect the voltage, ground, and data wires in that order. He utilized colored wire markers to keep track of which was which during assembly. The controller and power supply were fastened to the back with simple clips and wooden blocks. A French cleat system on the back makes it simple to mount the complete panel to a wall. Once he had everything configured inside the WLED interface, it was only a matter of selecting the SK6812 type, validating the 12-volt system, and specifying the 50×50 pattern with a vertical zig-zag orientation. Some brightness limitations were set to protect the power supply, and four data outputs were allocated to each block of LEDs. Once everything was saved, the display would respond promptly to requests for colors, effects, or scrolling messages.

The Department of Homeland Security (DHS) is reportedly developing smart glasses that could be used to collect intelligence on immigrants and US citizens, journalist Ken Klippenstein reported. The devices would help ICE agents identify “illegal aliens” from a distance by capturing video and comparing it to biometric data like facial recognition and walking gait, according to budget documents seen by Klippenstein. The DHS wants to deploy the “ICE Glasses” by September 2027.
“The project will deliver innovative hardware, such as operational prototypes of smart glasses, to equip agents with real-time access to information and biometric identification capabilities in the field,” the document states. The glasses could allow agents to compare observed subjects against existing biometric databases and identify them in real time during interactions.
Such devices could help make surveillance of US residents “ubiquitous,” according to the report. “It might be portrayed as seeking to identify illegal aliens on the streets, but the reality is that a push in this direction affects all Americans, particularly protestors,” a DHS lawyer speaking on the condition of anonymity told Klippenstein.
The deployment of such devices is worrying to civil liberty groups, particularly in light of recent law enforcement activities under the Trump administration. The FBI was reportedly directed by the Department of Justice to “compile a list of groups or entities” who demonstrate “anti-Americanism,” according to a previous Klippenstein investigation.
It’s not the first time smart glasses have come up in reports about the DHS. An investigation by The Independent last month found that ICE and Border Patrol agents in six states were using Meta’s AI smart glasses of their own accord, in possible violation of DHS rules. Congress has reportedly been notified of the DHS’s Ice Glasses project but has yet to comment publicly.
The Complete Arduino, Raspberry Pi, and ESP32 Bundle has 14 courses covering what you need to get started on building out your own smart home. After learning the basics, courses show you how to create a weather monitoring system, a smart home security system, a plant watering system, and more.
